(o1. ss-47) This invention relates to'an ophthalmic mountingV vandl has forone vof its objects the provision 'of"rr'ieans'V for` mounting 'a'strap upon a lens securely Without theA usual dangers of breaking the Another object of the invention is the provision of a construction which will apply suiiicient pressure upony the lens by resilient-action to hold? the .lens 4securely Without danger ,of cracking Vor breaking the lens when setup'to the desired tightpo'sitionr' l "i C Another objectof theinvention is the provision off'aV constructionv which will apply suincientv 'pressure-i upon 'the-'retaining screw or bolt fo'1""-sec1'1ringV the strap to'the lens to prevent" the bolt-frombecoming accidently loosened, f

VAnother object of the invention is the provision of a construction by which the hole through the lens strap and the hole through the lens need -not Vbe "accurately lpositioned for securely holding the lens'v and 'strap tdgether.

In the attaching of bridges, temples, nose pieces or the like parts fof ophthalmic mountings to rimless lenses a so-called strap is usually provided having a basevk and spaced ears to extend over the opposite surface of the lens, the ears are perforated and the lens perforated through Which there extends a securing bolt or screw to hold the parts'assernbled. In the setting up of this screw inthe strap, ifthe same is turned in too tight the lenses are'cracked, brokenfor splintered around the opening, also if the. hole inthe lensis not the correct distance from the edge, then the openings through the ears ofthe 'strap do not properly align and if pressure is applied in securing these parts, the lens is apt Vto splinter or break or elseit is not held tightly in position, and in order to avoid both of these undesirable results in'a unit construction I have provided a lining member in the strap Which is resilient and Will not only serve to engage the edge of the lens to secure and tight connection with reference to aligning for the holes in the ears of the strap and the holein the lens, but will also serve to absorb pressure ordinarily applied to the sur- `face of the lens to hold the same insecure position and will enable a settingup ofthe securing bolt or `screw to the desired amount whereby the [strap is rmly and securely held in the lens With- -out the breaking off-the same as has been frequently experienced in practice, and the following is a detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous re- ,sultsmay be accomplished.

With' reference to the drawing have illustrated a lens l5 which is shown generally cirvcular Valthough other polygonal'shaped lenses such desired. This strap consists of a base 2U; arcuate on itsinner surface and ofa curvature of less n radius than the curvature of the lens Which it is to receive. Ears 2l extend generally at right angles to this base 2U and are' perforated asv atV 22, one of whichperforations is threaded. atr23 to receive a threaded securing bolt 24 therein. A liner designated 25 is of a. shape generally conforming to the shape of the strap and is posi- The portion 26 of this spring liner is'on the arc of a circle of less radius than the edge of the lens with which it is to contact so that it will engage the lens at its outer edges' 21 while its portion, inwardly from the ends thereof, willv engage the base of the strap preferably at the ends of the strap 28 to provide a more secure engagement therewith. This member 25 is provided with projecting portions 29 perforated as at 30 to receive the bolt 24 and in the showing in Fig. 2 tongues 3l are provided to extend inwardly and engage the opposite surfaces of the lens I5 and apply pressure thereagainst.

By this arrangement the strap is permitted of adjustment or relative movement with reference to the lens for the alignment of its holes 22 and 23 with the hole 32 in the lens while securing firm engagement therewith in several relative positions of adjustment and also as the bolt 24 is drawn in and the ears 2| ofthe strap tend to move toward each other, the resilient tonguel 2| serves to resist this movement and when a firm engagement is had there is still room for more compression and the lens is thus held firmly without wabbling or swinging in either of two planes at right angles to each other thereby providing a rigid connection of the parts and a desirable secure engagement of the strap with the lens.

In some instances, instead of providing a single tongue as 3l I may provide a pair of tongues shown as 33 and 34 in Fig. 6. In other instances the ears of the spring may be cupped as at 35 shown in Figs. 'l and 8, with a sufficiently large opening as at k3!) so that the contact 40 and 4I of each of these ears with the lenses will permit some movement inwardly and outwardly relative to the strap for the vresilient action desired. 1n other cases the strap 4I may be recessed as at 42 to receive a single tongue 43 therein as shown in Fig. 9, or a double tongue 43 and 41 as shown in Fig. 13, by which arrangement the ears may be bent toward each other lby a pair of pliers lWithout the danger of unduly flexing the spring to seat it as might otherwise occur. In Fig. 11 I have shown a still further modified form of cupped ears 44 slit as at 45 to permit of resilient action and to provide a plurality of fingers 46 or tongues for engagement with the lens.

In some cases I may turn the edge of the spring liner inwardly about the opening 3|! in the ears, as at 49 in Fig. 9, to enter the hole inthe glass lens and better protect the edges of this hole from splintering.

The liner or spring may be secured to the strap through riveting or upsetting of one of the parts, such as rivet 48 over the liner, and thus a unit construction may be provided and a construction having the functions of securing the lens by vengagement with its edge as well as by engagement with its opposite surfaces to prevent breaking and provide a secure connection which may be used at either the bridge or the temple side ofthe lens. Also this resilient liner or spring serves to absorb any shock received on the metal parts or bridge or temple and prevent their transmission thereto;

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all themechanic'al changes to which the device is susceptible, the 'invention being defined and limited only by the terms of the appended claims.
